• Solar – Low penetration in diesel communities (20%)

• Wind – Low penetration wind – Sachs Harbour (20-30%)

• Wind – High penetration with storage

• Mini-Hydro – Lutselk’e, Deline, Kakisa

Short to Medium term Vision for

the NWT Power System

Colville Lake, NT

• Diesel Efficiency

Variable Speed Engine pilot – Aklavik – World’s first-in-field

Hydrogen injection pilot – Deline

• New Mines

• BESS – Bulk Energy Storage System (Batteries)

Replicate Colville Lake’s battery success in thermal zone

Snare system – share hydro with battery – less diesel

Short to Medium term Vision for

the NWT Power System

Long Term Opportunities

• Expand Taltson Hydro System

• Connect to the Continental Grid

• Geothermal

• Nuclear – Up to manufacturers to test and validate this technology

• Develop hydro on the Mackenzie River
